Mourinho met the squad last week at United's Carrington training base and is ramping up preparations ahead of Saturday's pre-season opener at Wigan.

United released their first batch of training photos under Mourinho on Wednesday and the Portuguese posted a positive message to them on his Instagram account.

"After 10 training sessions I can say: 'I love to work with these guys," Mourinho wrote.

New signings Henrikh Mkhitaryan and Eric Bailly were among those in training, as well as 18-year-old defender Axel Tuanzebe, who could make his senior United bow at the weekend, along with 17-year-old right-back Tyrell Warren.

"I don't know them well but I just trust Nicky Butt, [head of football development] John Murtough and the structure's judgement," Mourinho said last week. "When they say we have a few players who, in a couple of years, can be first-team players."

Also among those in training was Luke Shaw, who could make his comeback 10 months on from breaking his leg in Eindhoven.

A number of those in attendance, could however, be moved on by Mourinho over the coming weeks.

"We have brought a few new faces in, we will keep some others but, in the end, it doesn’t matter who the manager is, it doesn’t who the new players are or who is staying or leaving," Mourinho said earlier this week. "It’s Man United and Man United is much more than any one of us."
